Are there any out of the box ways in Houdini to visualize group membership in the viewport (before I make my own using attributes)?

Thanks!

For quickie visualizations, I just use the Select tool. eg. hit ‘s’, choose the point/primitive selection type, from the toolbar above the viewer: choose the group and click on the “replace selection with group” icon. If you want to only see/hide the group, then I choose it from the visibility pulldown menu, this creates a Visibility SOP with the group.

Ah that works great! Thank you!
